Be itknown that I, ARCHIBALD MCGILLIS, citizen of the Dominion of Canada, residing et Vancouver, in the Province ozt Brit-ish Columbia, Genade, have invented a. new und useful EXcavetingSc00p v :tor 'Wire-Rope Heule, of which the following vis e specieation. f

This invention Vreliites to an excevoing scoop' or scraper vof that class, which is drown by e Wire rope over the ground to be excavated, and when loaded is by the seme,4

ineens conveyed .to the'dump, sind my ob ject hits beenI to Vprovide e scoop of this class that will, in use With'en ordinary 1wire rope heul and haul beck' linemutometieellv disengage and engage' .its connecting hooi: from the piaeeof its connection to the scoop and by changing this `platee of connection in relation `to the sera-ping edge of' the. scoop will change the action of itso that the eterne honiing rope serves or excevavtin for deiivery o" the scoop to the dump or place of deposit, and for .overturning itI there,

and by the heul beck the scoop moy be righted and returned to the pla ce of exceso.- tion.

The-invention oise comprises :t provision by which, during the beeki'erd heul, a pair of Wheels ere drown under 'the scoop end save the dragging o'f it on the ground, es is usuel.

The inrention is pertiouieriy described in. 'the following specification, terence being Iliade to the drawings by which it nccomponied, in which:

sides and back. The scraping or excavating edge of this scoop is provided with teeth 3 projecting-beyond it, which teeth :ire carried under the bottom and round the bend of thobaek to take the weer of these parts.

Toward the upper` port of-the sides :at the back, handles 4 are secured to facilitate menipuiation by the attendant.

A forward hauiing bail 6 is pivoted et 5 on the sides of the scoop as close as pref ticable to the bottom und forward edge of it, which bnii is at the-middle line provided with a ring .7 for the attachment of the hook 8 of the hauling line 9. Theshank of this hook 8 is passed through the ring and hooks outward and Ato the bend of the hook,'prferably ltoward the point, so that .in its redini length than the other so as 'to teli weil Within it, as shown in Figh. To this boil the hook 8 iseonnected when it is desired to exeavete and fill the scoop,

In order to prevent the scoop from unduly digging' into the earth and possibly overturning, if the eert'h should htippen to be Very ,tenacious or herder than usuel, the upward movement of the haii 12 is iimited by a hook lever 13 link connected et 14. on each side of the scoop. When this check is required the hook of it is, by moons of the lever end, passed over the bail. t

To the upper edge of the beek of theisooop .in the middle line n loop 15 is scented1 in which the hook of the hauling line is placed when the sooopjs to be overturned,

lhe heul berk boil i7 is pivoted :it 18 on each side of the scoop toward the bock und is provided with :i ring 16 through which the haul back line l0 posses ond meninst 'which the bend'of the hook 8 engages when the lino'iis drawn buck. Finch end o'lthis haii i7 is provided, as et 19 beyond the pivots 1S and curved toward, the back 1fewer odge of the scoop und these ends ere furnished with wheels 20. When the scoop moving foi-Word these Wheels nre ciear of the/ground, but during thebecit- Ward haul the lever ends 19 of it aremoved Adownward and forward and carry the Wheels 2O 'under the scoop where they will sustain it and suhtitute the Wheel resistance for the drag. f

A strong loop 2l is secured to the 'nach of the scoop near the bottom to which the haul hack line may he connected when it is not desired to use the haul hach hail 18, 19 with its connected Wheels 20.

In use the scoop 2 is drawn to the place of excavation on Aits Wheels 20 hy the haul hack line l0, the henrl of the hook 8 en: gaging the ring 16 of the hail 17 through which the line l0 passes.

On arriving at the place of excavation the direction of haul is reversed, anr'l the hauling lino 9, which passes through the ring 7 of the hail (i, is drawn through that riuf,r and the hook 8 automatically hooks itselfv into llie excavating hail l2. The connection of this hail 6 to the scoop being so much above the excavating enige of it, (hat edge with its 'teeth digs in and the hach of the scoop is uptilted permitting the excavating edge to Scrapethe gri'mnd and fill the scoop; the check hooks 13 being used Where the charm acier of the earth is particularly heavy, to limit the tilt.

lll/hen the scoopis full the hook S is disengaged from the excavaling hail 12, and when the pull is again exerted the hook 8, the line il of which passes through the ring 7 of lhc hail l5, automatically hooks itself in that ring, and llie scoop is drawn tov the plan.. ol' deposit, the hail being connected near the bottom edge of lhe scoop t0 prevent the excavating edge lfrom digging in. Un arrival at the place of deposit, the hook i is, hy ille attendant, connected into the oven -liurning loop l5 on the hack eflge of the scoop, and further Vlmavard haul overl'ulne the Scoop and deposits ille eonlezils.

When the haelm'ard haul is conunencefl, lhe hook S :ultotuatically (lisengagee itself from the ovcirlurning loop l5 anal the bend ol the hook is by the haul hach: line 10 drawn into engapyrrncnt with ille ring 16 or' the hail i?, ami by' the action hc'l'orc errplaincrl, the whccle ill are drawn under the scoop 1go relieve ille hafliwarll haul.
